Tillage effects on soil water redistribution and bare soil evaporation throughout a season
Tillage-induced changes in soil properties are difficult to predict, yet can influence evaporation, infiltration and howwater is redistributedwithin the profile after precipitation.We evaluated the effects of sweep tillage (ST) on near surface soil water dynamics as compared with an untilled (UT) soil during a 7-month period. Plots were established in a fallow field devoid of residue under stub...
متن کاملRemote sensing of crop residue cover and soil tillage intensity
Management of plant litter or crop residues in agricultural fields is an important consideration for reducing soil erosion and increasing soil organic C. Current methods of quantifying crop residue cover are inadequate for characterizing the spatial variability of residue cover within fields or across large regions. Our objectives were to evaluate several spectral indices for measuring crop res...
متن کاملEffect of long term no-till and conventional tillage practices on soil quality
Management systems influence soil quality over time. A randomized block design in 2 (tillage system) 3 (crop rotation) factorial arrangement was laid-out to evaluate the impact of tillage and crop rotation (2002–2007) on soil quality. Conventional tillage and No-till were factored into continuous corn, corn–soybean, and corn–soybean–wheat–Cowpea systems. Ten soil cores were collected at 0–7.5, ...
متن کاملLong-term tillage and residue management effect on soil compaction and nitrate leaching in a Typic Haploxerert soil
A field experiment was conducted to compare the effects of long-term tillage and cropresidue management on some physical properties and nitrate leaching of a Typic Haploxerertsoil under winter wheat (Triticum vulgare L.)-soybean (Glycine max L.) double-croppingsystem. The tillage systems consisted of conventional tillage with stubble (CT1), conventionaltillage with stubbles burned (CT2), heavy ...

Soil microenvironments are different in fields that have surface-crop residues than in tilled fields Conservation tillage fields provide different environments for biowith incorporated residues. Natural-resource simulation logical and chemical processes than tilled fields. Our understanding of decomposition does not adequately account for post-harvest residue models that address s...
